I agree with Sigma, just get rid of the whole used market brokers. You start with some either 1VL, 3L, 5M, or 10S. Or maybe just give a set amount of money like usual and have a one day used market with unlimited planes to do whatever you want. Then after that, the used market become strictly when airlines go bankrupt, the planes end up there. The beggining of the game would have to be perfectly planned out to expand rapidly. The used market is playing too much of a role in this game, it's the entire game, it ruins strategy, it ruins the fun aspect because you just have to sit on the UM, and we all now how much the first 3 months of the game means, it means basically the whole game.
By the way, I want to say sorry because I will admit that I did complain a little about how the used market was getting ridiculous. Sami, it must be impossible to deal with all this, and run the whole thing, and I hope your getting something out of all this.
